Purely visual at the beginner, didn't open the window nor the window frame... since spaceweather said the sun is spotless these days.

Used a 13mm Nagler, very sharp and great view, two filaments stretched across the solar disc at nearly 1/3 disc length, a nice cluster of prominences can be seen as well... Short but very wide.

Finally can't held myself from imaging using a color webcam which is the only thing I had at this moment. Black white mode does help on focusing but still, I've overexposed it and thus only a small part shows detail.

I didn't take any photograph today, but I did observe with my binoviewer, there seems to be 3 long filaments in the 1/3 part of the disc, but careful examination seems to reveal that they're actually ONE SINGLE crazily long one, it spans at least half of the solar disc

however, it tends to say it's not continuous, with more careful look, you can see in some parts they're really too thin to say it's connected.

there're some nice prominence at the edge, one is especially fun to look at!!! it looked like a inverted M attached to the solar limb, or shall I say it's a W!!!

841 is the single most attractive active region in my finder sized 40mm system.

Finally, I waited for sun to set on a remote building and it's really a great site in H-alpha!
